Johnny Cash 'Hurt'[QT Video]: Every day, for the months before Johnny Cash died, he'd call Rick every day to give him communion, saying "And they retired to a large upper room for the Passover feast, and Jesus picked up the bread…" and so on. Have you ever heard anything cooler than that?

LL Cool J 'Going Back to Cali'[iTunes link]: Maybe the best ever use of an 808 in a hip hop record?

Beastie Boys 'Rhymin' & Stealin'[iTunes link]: When I was 15, this was the coolest thing I'd ever heard. If you're in any doubt about Rick's skills, listen to this cover version by comedy voice-over man turned hip hop 'artist' Penthouse J.

Jay-Z '99 Problems'[QT Video]: Rubin says all the music he likes is punk. AC/DC are punk, the Beatles are punk, and hip hop is 'black punk'.
